MEMS Mics Offer High SNR, Low Power

Synaptics showcases its AudioSmart solution for Amazon Voice Services using InvenSense high performance MEMS microphones. The ICS-40212 and ICS-40720 analog output and the ICS-41350 PDM digital output MEMS microphones are approved for use with the Synaptics AudioSmart AVS solution. These microphones offer high SNR and very low power at a frequency bandwidth up to 20 kHz. The TDK and Synaptics technology combined are enabling smart speakers, home hubs, and Internet of Things (IoT) applications to achieve their full potential. Key applications include:
